DYNAMO SUSPENSION.

Application filed June 18, 1915.

To all whom it may concern:

Be it known that I, WILLIAM F. BoUoHn, a citizen of the United States, and a resident of Buffalo, county of Erie, State'of New York, have invented certain new and useful Improvements in Dynamo Suspensions, of which the following is a specification.

My invention relates to improvements in arrangements for supporting dynamos on 1 car trucks. One object of my invention is to provide a simple and efficient arrangement or structure, having few parts, easily constructed and put together and so arranged that they do not interfere with other apparatus on the car. Further objects, features and advantages will more clearly appear from the detailed description given below, taken in connection with the accompanying drawings, which form a part of this specification.

In the drawings Figure 1 is a plan view of a portion of the car truck with my'improvements in one form arranged thereon. F ig. 2 is an end view of parts shown in Fig. 1. Fig. 3 is a section taken onthe line 83 of Fig. 1. Fig. 4 is a side view of parts shown in Figs. 1 and 2. Fig. 5 is a detail looking in the direction of arrows 55 of Fig. 1. Fig. 6 is a detail side view of one of the sliding supporting blocks, from which the generator or dynamo is pivotally suspended. Fig. 7 is a view looking in the direction of the arrows 7-7 of Fig. 6. Fig. 8 is a section taken on the line 88 of Fig. 6. Fig. 9 is a plan view of parts shown in Fig. 6. Fig. 10 is a perspective illustrating the arrangement of the axle pulley on the axle.

Referring to the various figures, 1 represents a car truck having side sills 2, a depressed end sill 3, safety sills 4: suitably carried upon the car axles, one of which is shown at 5, provided with the usual car wheels 6. Rigidly secured to the truck, adjacent the side sills 2 and extending outwardly, horizontally from the truck, are two parallel supporting bars 7, one on each side of the truck. At their outer ends these bars are bent backwardly at 8 and secured to the outside of the truck by bolts 9. The rearwardly extending portions of these bars have bar portions 10, which for a short distance extend parallel to the outwardly extending bars 7.- Upon one set of the parallel.

Specification of Letters Patent.

Serial No. 34,865.

extending bars 7, 10, is arranged a sliding block 11, adjust-able longitudinally of the bars 7, 10, provided with upwardly extending cars 12, through which passes pivot bolt 13, surrounded by a bearing bushing 1%, so arranged that the bolt 13 oscillates with the members or portions 30 hereinafter referred to, (see Fi e. 6 to 9). The block 11 is also provided on each side with downwardly extending cars 15, which are securely clamped to the parallel bars 7, 10, by means of screw bolts 16 and lock nuts 17 Intermediate the bars 7 and 10, the block 11 is provided with integral spacing webs 18, each provided with a reinforcing rib 20. 21 and 22 represent two hooks, the hook 21 engaging about the underneath side of the bar 10 and the hook 22 engaging about the underneath side of the bar 7. The shanks of these hooks extend upwardly through the block 11 and are secured thereto by means of nuts 23 and lock nuts 24.

By loosening the books 21 and 22 and the clamping bolts 16, block 11 is adjustable longitudinally of the bars 7 and 10, and upon tightening up of the screw bolts 16 and hooks 21 and 22, the block 11, which slidably rests upon the bars 7 and 10, may be secured in its adjusted position.

Carried upon the other pair of parallel bars 7 and 10 is a block 25, provided with similar upwardly extending cars 26, carrying a similar pivot bolt 27 and surrounding bearing bushing. The block 25 is likewise provided with similar inte ral spacing webs and reinforcing ribs 18 and 20 (not shown in connection with block 25). The block 25, however, is provided with cars 28 extending downwardly, two on the inside of the bar 7 and two On the outside of the bar 10, and bolts 29 pass through the inner and outer ears respectively and bars 7 and 10, in order to firmly and non-adjustably sccure the block 25 to the bars 7 and 10. Pivotally supported by the blocks 11 and 25 and about the pivot bolts 13 and 27 is a swinging \l-shaped member, having downwardly extending parts or portions 30, and a base or horizontal cross portion 31 on which a dynamo 32 is non-adjustably secured, by means of clamping plates 33. The clownwardly extending portions 30 at the upper 3 1 (see Figs. 2, 3 and Extending etween the downwardly extending portions 30, but above the base or cross piece 31, is a cross-bar 35, formed of an angle iron, and at each end clamped to the portions or parts 30 by means of clamping plates 36; A plate 37 has one end secured to the angle cross bar 35 at 38, and at its other end is bent over to the shape of the dynamo 32 and apertured to accommodate an integral lug 39 on the dynamo 32. The plate 37 is bolted to the top of the dynamo by means of bolts 40. In this way the dynamo 32 is rigidly secured to the swinging member, comprising downwardlyextending portions 30 and base 31, the dynamo being supported on base 31 in such position that the axis of the pivots l3 and 27 lies substantially directly over the axis of the dynamo, so that the center of gravity of the swinging parts lies substantially directly beneath the pivotal axis. The

dynamo is provided with a pulley ll and the axle with a pulley 4:2 and a belt 43 passes over these pulleys, for the purpose of driving the dynamo from an axle 5 ot the truck.

In order that the pulleys 41 and 4c2 may be brought into proper alinement, the pulley 42 is adjustable along the axle 5. To this end the pulley 42 is made in two halves and provided with a two piece bushing 44, as shown in Fig. 10. When it is desired to ad just the pulley to a different position on the axle 5, in order to bring it into proper alinement with the pulley 4.1, the clamping bolts, which clamp the two sections of the pulley 42 together, are loosened and the pulley, with its bushing, is then moved to the desired position on the axle 5, whereupon it is then clamped in the proper adjusted position.

For the purpose of alining the axis of the dynamo to bring it parallel with the car axle, the hooks 21 and 22 are loosened, as well as the screw bolts 16, and the block 11 is thenadjusted longitudinally of the bars 7, 10, until the axis of the dynamo is parallel with the car axle, whereupon the hooks 21 and 22 and bolts 16 are again made to firmly clamp block 11 in place on the bars 7 and 10.

A cross bar 50 rigidly connects the outer ends of the supporting bars 7. Cross bar 50 is preferably made of a piece of angle iron and has a centrally depressed portion 51. Carried by and cooperating with the centrally depressed portion 51 is a tension device, comprising a'link 52, passing through an aperture in the vertical web of the angle crossbar 50 and pivotally connected to the cross bar 35, at 53. On. its outer end the link 52 is surrounded by coil spring 54-, com pressed thereon against the bar 50 by means o-f'a hand nut 55, so that upon operating the hand n.ut55, the tension with which the spring 54- tends to move the dynamo away from the truck and keep the belt taut, may be adjust-ed. By arranging the end sill 3, cross bar 50 with centrally depressed portions, and arranging the bar 35, so that it does not extend above the depressed portion of bar 50, there are no parts of the arrange ment which interfere with the center beams of the car or other devices secured thereto at this point.

Lug 39 on the dynamo isprovided with an aperture through which extends a pin 60 provided with cotters in each end, pin 60 being outside of the end of plate 37. In case bolts 40 should fail to hold the dynamo rigid with plate 37, the lug 39 and pin 60 will maintain the dynamo inposition and this acts as a safety device.

It will be seen that the dynamo is easily accessible at all parts thereoiand is easily removed for repairs. To remove the dynamo it is only necessary to remove the cap plates 31 and the bolts at 38, or the bolts at 40 and pin at 60, when the dynamo may be readily slipped off the support at 31, the belt 13 being removed.

Vl hile I have described my improvements in great detail and with respect to the preferred embodiment thereof, nevertheless. I
